LibreABC

Thomas Kerboul, de la Bibliothèque de Genève, animera un atelier lors de la journée #LibreABC2025 sur les jeux de données dans #Wikidata.
#SPARQL #RDF

Description:
Wikidata est une base de connaissances libre et ouverte offrant un accès à des données structurées. Au-delà de la consultation élément par élément, Wikidata permet de visualiser une grande quantité de données sous forme de tableaux, de cartes ou encore de chronologies et de créer ses propres jeux de données grâce au langage SPARQL.

In this blog post at s.gwdg.de/m5Bu3L I showcase the #NFDI4BIOIMAGE (@nfdi4bioimage@nfdi.social, @nfdi4bioimage@bird.makeup) #knowledgegraph and its function as a registry for public #OMERO image data repositories and their respective #SPARQL endpoints. Annotated #bioimage data has become part of the #semanticweb. @joshmoore @Andrawaag #nfdi #metadata #KnowledgeGraphs #ontop #r2rml #rdf

SciComp BlogLinked Open Data for BioimagingThis post demonstrates the NFDI4BIOIMAGE Knowledge Graph (N4BIKG). Many aspects of this project are still very much in the flow including a consensus on which ontologies and terms to employ, how to define various namespaces and much more. These issues left aside, I focus on two components: First, the "core" KG contains information about the NFDI4BIOIMAGE consortium, it's participating institutions and people working in or for NFDI4BIOIMAGE, publications (via zenodo records submitted to the NFDI4BIOIMAGE community) and some more.

#wikidata est essentiel dans les projets #OpenData, notamment dans les institutions patrimoniales, qui ont tout intérêt à compléter des propriétés qui les concernent.

Les requêtes #sparql permettent par exemple d'associer des images de provenance différentes dans une galerie, avec les liens vers l'institution d'origine.
Voir aussi la somme de toutes les #peintures.
Il existe 2300 catalogues construits à partir de requêtes dans #wikidata, des listes d'#expositions...

@daieuxetdailleurs

Le rêve : répercuter les données sur #wikipedia et avoir des données intégrales sur préfets, sous-préfets, secrétaires...

On peut effectuer des requêtes en #sparql, en utilisant resonator pour une visualisation plus didactique, avec notamment une frise chronologique : voir histropedia pour les préfets de l'Aube.
Merci au roi de la requête @belett 😁

Elle ajoute aussi des #signatures et des #portraits sur #wikicommons

Bravo pour cette intervention 👏

W3C Developers

Last April, @fabien_gandon highlighted how @w3c #LinkedData standards (such as RDF, SHACL, and #SPARQL) enable knowledge extraction, sharing, and machine learning across domains like #robotics, culture, medicine, and chemistry. These standards support interoperability, agent collaboration, and distributed #AI. He concluded his talk with a call to address AI's impact on user attention and to encourage ethical dialogue within the W3C community.
